We recently stumbled across a Reddit thread cataloguing some minor mistakes in some of the biggest songs of all time, and while we didn't think we'd notice most of them, we now can't unhear them.
Rather than keep the 'joy' of these discoveries to ourselves, we decided to share some of our favourite ones that we found thanks to the thread, so you can notice them and share them with those around you.
Some of them are funny, some are confusing, but all are unforgettable once you've noticed them for the first time.
It turns out that in Lady Gaga's Perfect Illusion, there's a fart at 2:48. We're amazed at how crisp it sounds.
We're not quite sure what's going on with the glitch in Britney Spears' Alien - you can hear it at 2:14 as she sings "and the light in your eyes". One of the writers of the track, William Orbit, hinted that Black Eyed Peas' will.i.am might be at fault, as he served as the track's executive producer.
M.I.A's Paper Planes stands the test of time, and for good reason. However, the transition between the verse and the chorus at 0:56 throws us off every time.
When BROCKHAMPTON were recording St Percy, they accidentally left on the click track - but all in all, it sort of adds to the track, don't you think?
Ever gotten to the end of something, and missed something you shouldn't have? That's exactly what happened on Taylor Swift's Changes - check out the snare hit at 4:05.
